Ducati North America boosted its market share across the United States in the first quarter of 2009, with record sales fueled by the Monster and Superbike line of motorcycles.

Ducati now boasts more than 10% of the sport and street bike sales in 20 key U.S. metropolitan markets, with the brand capturing 6% sales across the country.

“Ducati has come a long way in the last couple of years,” Michael Lock, CEO of Ducati North America, said in the press release.

“We have introduced business improvements, developed market-leading bikes, dominated international road racing and are very focused on the needs of our growing customer base. All of these factors have greatly contributed to our growing sales and market share success across the U.S.”

Ducati hopes to make further gains in U.S. market share later this month when it introduces its new sport bike, the Streetfighter.
